Rotation hinge
Abstract
A rotation hinge configured in a portable electrical device
includes a tube sequentially stringing a base coupled to a main
housing of the portable electrical device, a cam module and a
fixing plate coupled to a sub-housing of the portable electrical
device, and engaging with a riveting plate. The cam module has a
designed curve surface and at least two recesses positioned
thereon. Each section of the designed curve surface between the
recesses has an arc-shape projection portion. Each recess of the
designed curve surface contacts an elastic sliding portion. While
the cam module rotates, the elastic sliding portion moves from the
recess and moves along the designed curve surface. While the
elastic sliding portion contacts the arc-shape projection portion,
a compression force stored in the elastic sliding portion is
maximized. Therefore, the sub-housing is advanced to rotate by the
elastic sliding portion releasing the compression force.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a rotation hinge, and particularly to a
rotation hinge configured in a portable electrical device capable
of allowing a sub-housing of the portable electrical device
rotating on a main housing of the portable electrical device.
2. The Related Art
According to the current development of communication technology,
portable electrical devices such as mobile phones, personal digital
assistants and others, are capable of providing wireless
communication. One kind of the portable electrical devices includes
a rotation-type configuration. The rotation-type configuration has
a rotation hinge configured therein capable of allowing a
sub-housing of the portable electrical devices rotating on a main
housing of the portable electrical devices. In consideration of
carrying and downsizing issues, the sub-housing rotates above the
main housing to an open position for the operation purpose.
Otherwise, the sub-housing rotates to cover the main housing to a
close position for an idle or standby situation.
There is a rotation-type wireless communication device disclosed in
United States Patent Application Publication No. 2004/0018862. It
shows the wireless communication device including a first housing
with a housing support and a second housing positioned upon the
housing support, or a portion thereof, so that the second housing
may rotate around the housing support. Also, the second housing
includes a circular portion positioned upon the housing support,
and an extending portion extends from the circular portion. When
the device is in a closed position, the circular and extending
portions of the second housing are adjacent to the first housing.
When the device is in an opened position, the circular portion is
adjacent to the first housing and the extending portion is away
from the first housing. In addition, the second housing may have
multiple positions relative to the first housing in which each
position activates a particular function of the device.
However, the above described rotation-type wireless communication
device generally needs to be opened and closed by separately
gripping each housing portion and repositioning or rotating the
housing portion relative to one another. This generally requires
that the user free up both hands for opening the rotation-type
wireless communication device. Consequently, there is a need for a
self-operating opening and closed mechanism for configuring in a
hand-held portable electrical device to make the housing portion
self-rotating to one another.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a rotation hinge
configured in a portable electrical device capable of allowing a
sub-housing of the portable electrical device rotating on a main
housing of the portable electrical device.
According to the invention, the rotation hinge includes a tube
sequentially stringed a base fixed to the main housing of the
portable electrical device, a cam module and a fixing plate fixed
to the sub-housing of the portable electrical device, and engaged
with a riveting plate to make the base, the cam module and the
fixing plate sequentially stack. The cam module has a designed
curve surface with at least two recesses. Each section of the
designed curve surface between the recesses has an arc-shape
projection portion. Each recess of the designed curve surface
connects an elastic sliding portion.
While the sub-housing of the portable electrical device rotates on
the main housing of the portable electrical device by receiving a
external force, the cam module also rotates following the rotation
of the sub-hosing of the portable electrical device. The elastic
sliding portion moves from the recess of the cam module and then
moves to the arc-shape projection portion of the cam module
according to the rotation of the cam module, and thus stores a
compression force. While the elastic sliding portion contacts the
arc-shape projection portion of the cam module, the compression
force stored in the elastic sliding portion is therefore maximized.
In consequence, the cam module and the sub-housing of the portable
electrical device are advanced to rotate together because the
elastic sliding portion releases the compression force to press the
designed curve surface of the cam module.
Another object of the present invention is to provide a rotation
hinge configured in a portable electrical device capable of
allowing a sub-housing of the portable electrical device rotating
clockwise and anti-clockwise on a main housing of the portable
electrical device.
According to the invention, the cam module of the rotation hinge
has an upper cam and a lower cam. The upper cam has a first recess
and a second recess arranged at the designed curve surface.
Further, the lower cam has a third recess and a fourth recess
arranged at the designed curve. The arc-shape projection portion of
the upper cam adjoins one side of the first and second recesses.
However, the arc-shape projection portion of the lower cam adjoins
exclusive side of the third and fourth recesses. A first elastic
sliding portion and a second elastic sliding portion respectively
contact the first recess of the upper cam and the third recess of
the lower cam.
In this case, the cam module and the sub-housing of the portable
electrical device will be advanced to rotate clockwise together
according to the first elastic sliding portion presses the designed
curve surface of the upper cam by releasing the compression force
stored therein. Furthermore, because the designed curve face of the
lower cam is pressed by the compression force releasing from the
second elastic sliding portion, the cam module will be advanced to
rotate anti-clockwise. So the sub-housing of the portable
electrical device will be brought to rotate anti-clockwise via the
rotation of the cam module.
A further object of the present invention is to provide a rotation
hinge configured in a portable electrical device capable of
allowing a sub-housing of the portable electrical device rotating
on a main housing of the portable electrical device to an open
position.
According to the invention, the base has a block portion. A
rotation plate having an opening and a rotation disc having a
stopping portion are sequentially arranged upon the cam module. The
stopping portion of the rotation disc is arranged in the opening of
the rotation plate. While the sub-housing of the portable
electrical device rotates on the main housing, the rotation plate
also rotates to follow the sub-housing. The opening of the rotation
plate will connect the stopping portion of the rotation disc.
In this case, the rotation disc is advanced to rotate by the
rotation of the rotation plate after the opening of the rotation
plate connects the stopping portion of the rotation disc. While the
stopping portion of the rotation disc rotates to contact the block
of the base, the block blocks the rotation of the rotation plate
and the rotation disc. Therefore, the sub-housing of the portable
electrical device rotates on the main housing of the portable
electrical device to the open position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Firstly referring to FIG. 1, FIG. 2 and FIG. 5, a preferred
embodiment of a rotating hinge 100 according to the present
invention is configured in a portable electrical device 200. In
this case, the portable electrical device 200 is a mobile phone.
The rotating hinge 100 includes a tube 17 sequentially stringed a
base 1, a cam module 7, a rotation plate 9, a rotation disc 11 and
a fixing plate 13, and engaged with a riveting plate 15. Therefore,
the cam module 7, the rotation plate 9, the rotation disc 11, the
fixing plate 13 and the riveting plate 15 are sequentially stacked.
In this case, the base 1 couples to a main housing 201 of the
mobile phone 200 and the fixing plate 13 couples to a sub-housing
202 of the mobile phone 200.
The base 1 includes a receiving space 101 formed in an up surface
of the base 1. A first groove 103 and a second groove 105 are
horizontally formed in the base 1. The first groove 103 is arranged
higher than the second groove 105. One end of the first and second
grooves 103, 105 respectively leads to the receiving space 101. A
first through hole 107 perpendicularly through the base 1 is
arranged at a central area of the receiving space 101 of the base
1. A block 109 is positioned in the receiving space 101 of the base
1 and connects inner wall of the receiving space 101 of the base
1.
Referring to FIG. 1, FIG. 3 and FIG. 4, the cam module 7 is
received in the receiving space 101 of the base 1. The came module
7 has an upper cam 71, a lower cam 73 connected to the upper cam 7,
and a first engaging through hole 75 perpendicularly through the
cam module 7. The upper cam 71 has a designed curve surface 711, a
first recess 713 and a second recess 715. The first and second
recesses 713, 715 are positioned on the designed curve surface 711
respectively. The lower cam 73 also has a third recess 733 and a
fourth recess 735 respectively positioned on a designed curve
surface 731 of the lower cam 73. In this case, the first recess 713
of the upper cam 71 is opposite to the second recesses 715 of the
upper cam 71 and the third recess 733 of the lower cam 73 is
opposite to the fourth recesses 735 of the lower cam 73.
Furthermore, the first recess 713 of the upper cam 71 leads to the
fourth recesses 735 of the lower cam 73 and the third recess 733 of
the lower cam 73 leads to the second recess 715 of the upper cam
71.
Each section of the designed curve surfaces 711, 731 between the
recesses 713, 715 and 733, 735 respectively have arc-shape
projection portions 717, 719 and 737, 739. Further, the arc-shape
projection portions 717, 737 respectively adjoin the first recess
713 (FIG. 4) and the third recess 733 (FIG. 3), and are arranged at
a first side 75 of the upper cam 71 and the lower cam 73. The
arc-shape projection portions 719, 739 respectively adjoin the
second recess 715 (FIG. 3) and the fourth recess 735 (FIG. 4), and
are arranged at the other side 77 of the upper and lower cam 71, 73
opposite to the first side 75 of the upper and lower cam 71, 73. In
this case, the arc-shape projection portions 717, 719 of the upper
cam 71 are exclusively arranged to the arc-shape projection
portions 737, 739 of the lower cam 73.
Please refer to FIG. 1 and FIG. 6. A first elastic sliding portion
3 includes a sliding shaft 31, a compression spring 33 and a roller
35. Particularly, a second elastic sliding portion 5 is similar to
the first elastic sliding portion 3. The second elastic sliding
portion 5 also has a sliding shaft 51 and a compression spring 53
and a roller 55. For instances, the sliding shafts 31, 51 of the
first and second elastic sliding portion 3, 5 are respectively
passed through the compression spring 33, 53 and received in the
first and second grooves 103, 105. The roller 33, 35 respectively
couple to the sliding shafts 31, 51 and contact the first recess
713 of the upper cam 71 and the third recess 733 of the lower cam
73.
Referring to FIG. 1 and FIG. 2 again, the rotation plate 9 is
located upon the cam module 7 having a rotation space 91 formed in
a surface of the rotation plate 9. An opening 93 is opened at one
side of the rotation plate 9 and leaded to the rotation space 91. A
second engaging through hole 95 is formed in a central area of the
rotation space 91 and perpendicularly through the rotation plate 9.
The rotation disc 11 is received in the rotation space 91 having a
stopping portion 111 projected from an edge of the rotation disc 11
and located in the opening 93 of the rotation plate 9, and the
second through hole 113 perpendicularly through the rotation disc
11. The fixing plate 13 is located upon the rotation disc 11 having
fixing portions 131, 133 arranged at an edge of the fixing plate 13
for coupling to the sub-housing 202 of the mobile phone 200, and
the third engaging through hole 135 opened in central area of the
fixing plate 13 and perpendicularly through the fixing plate
13.
Still referring to FIG. 1 and FIG. 2, the riveting plate 15 is
located upon the fixing plate 13. In this case, the riveting plate
15 is an E-ring for securing and assembling purposes. The tube 17
includes a post-shape body 171, a bottom portion 173 arranged at
one end of the post-shape body 171 and a neck portion 175 formed in
another end of the post-shape body 171. Furthermore, a diameter of
the bottom portion 173 is bigger than a diameter of the post-shape
body 171 and a diameter of the neck portion 175 is smaller than the
diameter of the post-shape body 171.
Please refer to FIG. 1 and FIG. 2 again. While the rotation hinge
100 is assembled, the post-shape body 173 of the tube 17
sequentially passes through the first through hole 107 of the base
1, the first engaging through hole 75 of the cam module 7, the
second engaging through hole 95 of the rotation plate 9, the second
through hole 113 of the rotation disc 11 and the third engaging
through hole 135 of the fixing plate 13. Moreover, the post-shape
body 171 of the tube 17 engages with the cam module 7, the rotation
plate 9 and the fixing plate 13. In this case, the bottom portion
175 of the tube 17 contacts a bottom surface of the base 1 and the
riveting plate 15 engages with the neck portion 175 of the tube 17.
Therefore, the base 1, the cam module 7, the rotation plate 9, the
rotation disc 11, the fixing plate 13 and the riveting plate 15 are
sequentially stacked. That is to say, while the sub-housing 202 of
the mobile phone 200 rotates on the main housing 201 of the mobile
phone 200, the cam module 7, the rotation plate 9 and the fixing
plate 13 would be brought to rotate by the tube 17.
As shown in FIG. 5 and FIG. 6, while the sub-housing 202 of the
mobile phone 200 is in a close position, therefore the rotation
hinge 100 is in the close position, the block 109 of the base 1 is
arranged the opposite to the stopping portion 111 of the rotation
plate 9. The rollers 35, 55 of the first elastic portion 3 and the
second elastic portion 5 respectively contact the first recess 713
of the upper cam 71 and the third recess 733 of the lower cam 73.
The first and second elastic portions 3, 5 will be stored no
compression force if the distance between the rollers 35, 55 of the
first and second elastic sliding portions 3, 5 and the grooves 103,
105 of the base 1 is the longest.
Please refer to FIG. 7 and FIG. 8. While the sub-housing 202 of the
mobile phone 200 rotates clockwise on the main housing 201 of the
mobile phone 200 by receiving an external force, the cam module 7
would be brought to rotate clockwise by the tube 17. The rollers
35, 55 of the first and second elastic sliding portions 3, 5
respectively move out the first recess 713 of the upper cam 71 and
the third recess 733 of the lower cam 73. Therefore, the roller 35
of the first elastic sliding portion 3 moves to the arc-shape
projection portion 717 along the designed curve surface 711 of the
upper cam 71. Thus the first and second elastic sliding portions 3,
5 are respectively and progressively pushed to slide to the grooves
103, 105 by rotation of the upper and lower cams 71, 73 and the
sliding shafts 31, 51 respectively push the compression spring 33,
53.
Referring to FIG. 8, again, the distance between the rollers 35, 55
and the grooves 103, 105 are getting close. So the compression
springs 33, 53 of the first and second elastic sliding portions 3,
5 progressively store compression force by receiving a pushed force
from the sliding shafts 31, 51. While the roller 35 of the first
elastic sliding portion 3 just moves on the arc-shape projection
portion 717 of the upper cam 71, the compression force stored in
the compression spring 33 is therefore maximized and thus the
distance between the roller 35 of the first elastic sliding portion
3 and the groove 103 of the base 1 is the shortest.
Still referring to FIG. 8, while the sub-housing 202 of the mobile
phone 200 and the cam module 7 of the rotation hinge 100 still
rotate clockwise together, the roller 35 of the first elastic
portion 3 moves out the arc-shape projection portion 717 of the
upper cam 71. Therefore, the cam module 7 is advanced to rotate
clockwise by the compression force releasing from the compression
spring 33 of the first elastic sliding portion 3. The rollers 35,
55 of the first and second elastic sliding portions 3, 5
respectively move to the second recess 715 of the upper cam 71 and
the fourth recess 735 of the lower cam 73 along the designed curve
surfaces 711, 731 of the upper and lower cams 71, 73. The distance
between the rollers 35, 55 of the first and second elastic sliding
portions 3, 5 and the grooves 103, 105 of the base 1 is getting far
away.
In FIG. 6, while the sub-housing 202 of the mobile phone 200 and
the cam module 7 of the rotation hinge 100 rotate clockwise
together, the rotation plate 9 would be brought to rotate clockwise
by the tube 17. A first side 930 of the opening 93 of the rotation
plate 9 firstly contacts a first side 1110 of the stopping portion
111 of the rotation disc 11 for modifying a rotation degree of the
rotation hinge 100 and then the rotation disc 11 would rotate
clockwise following the rotation plate 9.
As shown in FIG. 9 and FIG. 10, while the sub-housing 202 of the
mobile phone 200 and the cam module 7 of the rotation hinge 100
rotate clockwise to an open position, in this case, the sub-housing
202 and the cam module 7 rotate clockwise to 180 degree, the
rollers 35, 55 of the first and second elastic sliding portions 3,
5 respectively contact the second recess 715 of the upper cam 71
and the fourth recess 735 of the lower cams 73. The distance
between the rollers 35, 55 of the first and second elastic sliding
portions 3, 5 and the grooves 103, 105 of the base 1 is back to the
longest. A second side 1111 of the stopping portion 111 of the
rotation disc 11 opposite to the first side of the stopping portion
111 contacts a first side 1090 of the block 109 of the base 1 and
then the block 109 blocks the stopping portion 111 rotating
clockwise. Therefore, the cam module 7, the rotation plate 9 and
the fixing plate 13 would stop rotating via the block 109 of the
base 1 blocking the stopping portion 111 of the rotation disc 9
rotating clockwise and thus the sub-housing 202 of the mobile phone
200 is in the open position.
While the sub-housing 202 of the mobile phone 200 rotates on the
main housing 201 of the mobile phone 200 anti-clockwise from the
open position to the close position by receiving the external
force, the rollers 35, 55 of the first and second elastic sliding
portions 3, 5 gradually move out the second recess 715 and the
fourth recess 735. The roller 55 of the second elastic sliding
portion 5 move to the arc-shape projection portion 739 along the
designed curve surface 731 of the lower cam 73. Thus the sliding
shaft 51 of the second elastic sliding portion 5 slide to the
groove 105 of the base 1 and pushes the compression spring 53.
Therefore, the compression spring 53 is stored the pushed force
from the sliding shaft 51 and thus the distance between the roller
55 and the groove 105 is getting close.
While the roller 55 of the second elastic 5 contacts the arc-shape
projection portion 739 of the lower cam 73, the compression force
stored in the compression spring 53 is therefore maximized and thus
the distance between the roller 55 of the second elastic sliding
portion 5 and the groove 105 of the base 1 is the shortest. While
cam module 7 of the rotation hinge 100 still rotates
anti-clockwise, the roller 55 of the second elastic portion 5 moves
out the arc-shape projection portion 739 of the lower cam 73.
Therefore, the cam module 7 is advanced to rotate anti-clockwise by
the compression force releasing from the compression spring 53 of
the second elastic sliding portion 5 and thus the sub-housing 202
of the mobile phone 200 would be brought to rotate anti-clockwise
by the rotation hinge 100. The distance between the roller 55 of
the second elastic sliding 5 and the groove 105 of the base 1 is
getting far away.
While the cam module 7 of the rotation hinge 100 rotates
anti-clockwise, the rotation plate 9 would be brought to rotate
anti-clockwise by the tube 17. A second side 931 of the opening 93
of the rotation plate 9 opposite to the first side 930 of the
opening 93 firstly contacts the second side 1111 of the stopping
portion 111 of the rotation disc 11 (FIG. 6), and then the rotation
disc 11 rotates anti-clockwise following the rotation plate 9. So
the stopping portion 111 of the rotation disc 11 would leave the
block 109 of the base 1.
While the cam module 7 of the rotation hinge 100 rotates
anti-clockwise to the close position, the rollers 35, 55 of the
first and second elastic sliding portions 3, 5 respectively back to
the first recess 713 of the upper cam 71 and the third recess 733
of the lower cams 73. The distance between the rollers 35, 55 of
the first and second elastic sliding portions 3, 5 and the grooves
103, 105 of the base 1 is still back to the longest. Therefore, the
sub-housing 202 also rotates on the main housing 201 of the mobile
phone 200 and back to the close position (as shown in FIG. 5).
Please refer to FIG. 11. While the rotation hinge 100 rotates
anti-clockwise from the close position to the open position by
receiving the external force, firstly, the cam module 7 rotates
anti-clockwise and the rollers 35, 55 of the first and second
elastic sliding portions 3, 5 respectively move out the first
recess 713 of the upper cam 71 and the third recess 733 of the
lower cams 73. The sliding shafts 31, 51 of the first and second
elastic sliding portions 3, 5 are respectively pushed to slide to
the grooves 103, 105 by rotation of the cam module 7. Therefore,
the sliding shafts 31, 51 respectively push the compression spring
33, 53 and the compression springs 33, 53 store compression force
by receiving the pushed force from the sliding shafts 31, 51. The
distance between rollers 35, 55 and the grooves 103, 105 are
getting close.
While the roller 55 of the second elastic 5 just moves on the
arc-shape projection portion 737, the compression force stored in
the compression spring 53 of the second elastic sliding portion 5
is therefore maximized and thus the distance between the roller 55
and the groove 105 is the shortest. While cam module 7 of the
rotation hinge 100 still rotates anti-clockwise, the roller 55 of
the second elastic portion 5 moves out the arc-shape projection
portion 737 of the lower cam 73. Therefore, the cam module 7 is
advanced to rotate anti-clockwise by the compression force
releasing from the compression spring 55 of the second elastic
sliding portion 5 and thus the sub-housing 202 of the mobile phone
200 would be brought to rotate anti-clockwise by the cam module 7
of the rotation hinge 100. Therefore, the distance between the
roller 55 of the second elastic sliding 5 and the groove 105 of the
base 1 is getting far away.
While the cam module 7 of the rotation hinge 100 rotates
anti-clockwise to the open position, the rollers 35, 55 of the
first and second elastic sliding portions 3, 5 respectively contact
the second recess 715 of the upper cam 71 and the fourth recess 735
of the lower cam 73. The distance between the rollers 35, 55 of the
first and second elastic sliding portions 3, 5 and the grooves 103,
105 of the base 1 is the longest. The first side 1110 of the
stopping portion 111 of the rotation disc 11 contacts a second side
1091 of the of the block 109 of the base 1 opposite to the first
side 1090 of the block 109 and then the block 109 blocks the
stopping portion 111 rotating anti-clockwise. Therefore, the cam
module 7, the rotation plate 9 and the fixing plate 13 would stop
rotating via the block 109 of the base 1 blocking the stopping 111
of the rotation disc 9 rotating anti-clockwise and thus the
sub-housing 202 of the mobile phone 200 is in the open position (as
shown in the FIG. 12).
While the sub-housing 202 rotates on the main housing 201 of the
mobile phone 200 clockwise from the open position to the close
position by receiving the external force, the rollers 35, 55 of the
first and second elastic sliding portions 3, 5 move out the second
recess 715 of the upper cam 71 and the fourth recess 735 of the
lower cam 73. The roller 35 of the first elastic sliding portion 5
progressively moves to the arc-shape projection portion 717 of the
upper cam 71 along the designed curve surface 711 of the upper cam
71. The sliding shaft 31 of the first elastic sliding portion 3
also progressively slides to the groove 103 of the base 1 and
pushes the compression spring 33. Therefore, the compression force
receiving from the sliding shaft 31 is progressively stored in the
compression spring 33 and the distance between the roller 35 and
the groove 103 is getting close.
While the roller 35 of the first elastic 3 exactly moves on the
arc-shape projection portion 717, the compression force stored in
the compression spring 33 is therefore maximized and thus the
distance between the roller 35 of the first elastic sliding portion
3 and the groove 103 of the base 1 is the shortest. While cam
module 7 of the rotation hinge 100 still rotates clockwise, the
roller 35 of the first elastic portion 3 moves out the arc-shape
projection portion 717 of the upper cam 71. Therefore, the cam
module 7 is advanced to rotate clockwise by the compression force
releasing from the compression spring 33 of the first elastic
sliding portion 3 and thus the sub-housing 202 of the mobile phone
200 would be brought to rotate clockwise by the rotation hinge 100.
The distance between the roller 35 of the first elastic sliding 3
and the groove 103 of the base 1 is getting far away.
While the cam module 7 of the rotation hinge 100 rotates clockwise
to back the close position, the rollers 35, 55 of the first and
second elastic sliding portions 3, 5 are respectively back to the
first recess 713 of the upper cam 71 and the third recess 733 of
the lower cam 73. The distance between the rollers 35, 55 of the
first and second elastic sliding portions 3, 5 and the grooves 103,
105 of the base 1 is still back to the longest. Therefore, the
sub-housing 202 also rotates on the main housing 201 of the mobile
phone 200 to back to the close position (as shown in FIG. 5).
The operation of the rotation hinge 100 via the first elastic
sliding portion 3 and the upper cam 71 of the cam module 7 to make
the sub-housing 202 be advanced rotating on the main housing 201 of
the mobile phone 200 clockwise to the open position and the close
position. Furthermore, the rotation hinge 100 via the second
elastic sliding portion 5 and the lower cam 73 of the cam module 7
to make the sub-housing 202 be advanced rotating on the main
housing 201 of the mobile phone 200 anti-clockwise to the open
position and the close position. The block 109 of the base 1 blocks
the stopping portion 111 of the rotation disc 11 rotating clockwise
and anti-clockwise for limiting the rotation range. That is to say,
the rotation hinge 100 only receives the external fore and then is
advanced to rotate clockwise and anti-clockwise to the open
position and the close position and thus the sub-housing 202 of the
mobile phone 200 is advanced to rotate on the main housing 201 of
the mobile phone 200 clockwise and anti-clockwise to the open
position and the close position.

form disclosed. Many modifications and variations are possible in
